`s o1aims.- c1. 1944) Y received vtogether Withthe mechanism Within -a This. inventionrelates Lto check controlledv mechanism and: checks forfoperating thesame.

I will" describeI my inventionas appliedto a vending-machinefbut it is to' be understoodthat vit is equally: applicable to other check controlled mechanisms; :such` and' the. like. v'

Y An object of the inventionis to provide' against operationof the check controlledV device by counj the lowermost article and projected into the terfeit checks by employing a check Vrequiring Ythe useofV expensivemachinery" to constructY andAv article. This is a common type of release mechwhich cannotltbe 'cheaply produced. `Whilelsuch a planf'for thepreventionof unauthorizedoperaf tion'of the-machine maynot'be universally yprac-l ticalg'fit is believedfthat'it will beV quite` practical in Automat stores "and in vgeneral `in places Wherefit is practicableto have' a cashier'present to selllthe` Vchecks and to redeem unused checks.v

A further object "of the invention is to provide forsecuring theabove indicated result by the' use 'of a mechanical check' 'having relatively movable parts incombination with a check controlled machineadapted to'"receivefsuchicheck and-to cause relative-motion Tof 1 its parts f nd-jthento respond tosuchrelativfmotionlto become opera-ffy tive-toi deliverymerchandisel'or otherwise livecome` V` eiective for fits intended vf'purposex 'f Amore specic obj-ect is to provide an expan-*f siblecheck as Well as a machine capable of causing 'such check to expand and to respond to such expansiontobecome'feffective for Vits intended:

purpose.

A 20 adapted to engage the arm I6 upon energiza- At one side of the magazine I2 is acheck slot '1,24 affixed vto the base I0 by aV suitable socket 25.k .Immediately A.beneath vthe platform^23 and posi- "tioned quite close Lto theV same are Lresilient contacts126. VV`These contactsfare positioned'sul'i-` ciently close to the platform 2'3 that theV weight' of the 'check Willdepress such platform against theresistance of the. spring 24 enoughto make contact `vbetween theelements 26. Such Ycontact completes the-circuit from line L rthrough a switch 21 and'conductor28 throughelementsrZS and 23'and conductor 29 to the magnets 30 in series and conductor 3| to L.

When this circuit is complete the magnets 3U l wil1-operate to cause expansion of the check, 4as

Willi be described. .When'the check expands the Y f upper surface thereof will fbridge the contacts-32 whereby to complete a circuit from L', through switch 21, conductor 28, contactV elements 32 and solenoidv II back'to L ,.f-Whereu'pon the plunger I8 `will-be moved to the fl'eft." n Y Plunger` I8 carries a plunger `rodY 33 around whichis a compression `spring 34 whichfwillfrestore the plunger to the position of Fig. 3 when the solenoid I1 is de-energized. The spring 34 is held at the left hand end against the action of the plunger rod by a suitable bracket 35. A suitable collar 36 on the plunger rod 33 may receive the other end of the spring 34. 'I'he plunger rod 33V carries at its left hand end by means of a suitable'bifurcated element 3'I a roller 38 which has a grooved periphery adapted to receive an angularly ldownwardly ext-ending `element 39.

Upon actuation of the solenoid, the platform 23 will be tipped over toward the left to dump the check. This will result in breaking the circuit between the elements 32 whereupon the spring 34 will restore the mechanism to the original condition shown in the drawings. The contact elements 26 and 32 may be suitably mounted on upstanding posts 40 composed of electrically nonconductive material and separated from each other by sleeves 4| also of insulating material.

The check may consist of Vupper and lower plates 42 and 43, either of which may be the upper, and a cylindrical shell portion 44 together Y with the internal mechanism carried by these elements. Movable within the enclosure defined by the elements 42, 43 and 44 are blocks 45 oi magnetic material, which preferably constitutes the sole magnetic portion of the check. These blocks are urged to central blocking position shown in Fig. 8 by springs 46 carried by the element 44. These blocks have reduced inner ends 4l adapted to engage in grooves 43 in elements 49 one of which is carried by each of the plates 42 and 43, as shown in Fig. 10. From this it will be clear that when the blocks 45 are separated, both the plates 42 and 43 willbe released and may separate under the action of springs 50. Limiting means are provided for limiting the amount of separation of the plates 42 and 43. Such means may take the form of inturned portions l carried by the elements 44 and receiving headed members 52 as best seen in Fig. ll.

It will be understood that a section taken through the lower elements 52 would be similar to Fig. 1l except that it would indicate that l diagonally opposed headed members are carried by the plate 42 and the other pair of diagonally opposed headed members are carried by the plate 43. Suitable guide means 53 carried by the element 44 may be provided for holding the blocks 45 in properly assembled relation. The spring 5@ may have such expansive properties that the weight of the blocks 45 will cause the check when in expanded position to present substantially the appearance of Fig. l2. After the check has been dumped from'the platform 23 it maybe recovered from thernachine, again compressed and sold forrepeated use.

While I have shown and described the preferred embodiment of my invention, I wish itV understood that it may be realized in numerous other embodiments and that I am limited only in accordance with the appended claims and the prior art.

Having thus described my invention, what I claim is:

1. As a new article of manufacture, a check, the same comprising a plurality of parts and means tending to cause separation of such parts, said check including means for normally holding such parts in contracted relation, means for limiting such separation of said parts and means responsive to an external magnetic influence for releasing said holding means.

2. In combination, a mechanical check com- Ya portion of said check prising a plurality of relatively movable parts, means tending to cause separation of such parts, means for normally holding said parts in contracted relation to each other, means responsive to an external iniluence for releasing said parts for separation, and a check controlled mechanism for cooperation with said check, said check controlled mechanism embodying means for releasing said holding means and means forming controlled mechanism and being responsive to such relative motion for rendering said check-controlled mechanism effective for its intended purpose.

3. In a mechanical check, separable parts, means tending' to separate such parts, latch means for holding such parts against separation and magnetically operable means for releasing said latch means. l

4. In combination with a check including separable parts, means tending to separate such parts, means for holding said parts against separation, and magnetically operable means for rendering said holding means ineiective, a check controlled mechanism including a housing, a platform in said housing, means for conveying said check tosaid platform, Ymagnetic means responsive to positioning said check on said platform for causing said magnetically operable means to function and means responsive to separation of said separable parts for rendering the said mechanism elective for its intended purpose and dumping said check from said platform.

5..In combination, a check including a plurality of parts movable with respect to each other, means for separating said parts, means for holding said parts together; a check controlled mechanism including means for rendering the holding means inelective whereby said parts separate under the action of the separating means, and means responsive to separation of saidV parts for rendering the check controlled mechanism effective for its intended purpose;

6. A mechanical check f or use in connection with a check controlled device, comprising, separable -parts, means tending Vto separate such parts, means for holding such parts against separation and means for releasing said holding means.

7. The combination of a check constructed in a plurality of axially movable, separable, diskshaped parts and a check controlled machine to be operated thereby, an element of said combination embodying means for causing relative motion of said parts axially of each other, and said check controlled machine embodying means for rendering said rst means active and means responsive to axial motion of said separable parts for rendering said check controlled machine effective for its intended'purpose.
